Letters Patent No. 91,973, lated June 29, 1869.

MPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all who/m 'it 'may concern.-

Be it known that I, J osIAH SHEPARD', of Newport, iu the county of Penobscot, and State of Maine, have invented a new and improved Oultivator; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in whichl Figure l is a side'view of my improved cultivator.

Figure 2 is an under-side view ofthe same. Similar letters of reference indicate corresponding parts.

My invention has for its object` to furnish an improved cultivator, which shall be so constructed and arranged, that it may be readily adjusted for turning the'soil towards or from the row of plants being cultivated, or to break down and level off ridges or rows of hills, or for` digging potatoes; and

It consists in the construction and combination of the various parts of the machine, as hereinafter more fully described. v

A are two small plows, which are so formed as to tum the soil in opposite directions, and the upper ends of the standards of which are secured to the forward ends of the two bars B.'

- O are two wheels, which are placed directly in the rear of the plows A, and the journals of which work in bearings in the supporting-bars D, the fmward ends of which are attached to the standards of the plowsV A, and the rear ends of which are attached to the rear ends of the bars B." 'lhc wheels C partiallysupport tlte machine, diminish the friction, and give steadiness to it while being used.

attached to the central bar F, to the rear end of which is attached the standard of the plow G, which is so the plows may be made toi-un shallower, or ont ofl the ground, by bearing. down upon the handles I, which are. attached to theurear part ofthe central bar F.

The movement of the rear end of the beam H is limited by the long staple or keeper h2, attached to the rear part of the central bar F.

K is a level', the rear end of which is pivoted to the rear end of the central bar F, and which is also pivoted to the rear end of the beam H,1so that the driver, from his seat L, by raising the free end of the lever K, can cause the plows to run shallower, or to run out ofthe ground, as he may desire.

Having thus described my invention,

' What I claim as new, and desire to secure by Letters Patent, is

l. The combination of the two small plows A, bars B, supports D, wheels C, central bar 11, and central plowG, having fingers formed upon the rear edges of its rings, with each other, substantially as herein shown and described, and for the purpose set forth.

2. The pivote'd tilting-beam H, pivoted lever K,

and staples h h?, arranged upon the frame B E F,

bearing the wheels C, as herein described, for the purpose specied. i
